🔎 UNIDENTIFIED strange rock found

[rockpassion]

I found this strange flat rock, which clearly has rust on it and veins Filled with iron oxides. So it must be iron rich i thought? But it does not atract a magnet. At least not visible, have not tried a string. Does not leave a streak and has a sulpher smell to it. Can a rock be iron rich without atracting a magnet?

Many forms of Fe are not magnetic. The color you see might be mostly stain. A little Fe stains a lot. You mentioned sulfur smell, pyrite is generally non magnetic. Crack it open and see what you really have.

It contains pyrite so pyrit nodule or layered pyrite rock. solved
